BACKGROUND OF THE INVENTION
The present invention relates to a bulk dispenser, in particular, a space is disposed through the storage tanks in the lower part of a plurality of storage tanks arranged in parallel, and the top of the bottom wall of the storage tank forming the bottom of the space. And moving a horizontally rotating wheel in the parallel direction of the plurality of storage tanks to pass the bulk material in the storage tanks through a slit-like outlet formed continuously on the bottom wall. The present invention relates to a bulk material dispensing device that dispenses on a dispensing conveyor disposed along a dispensing outlet below a wall.
[0002]
[Prior art]
Conventionally, for example, as shown in FIGS. 5 and 6, a hopper-type storage 1 for storing loose materials such as iron ore, coal, slag, and chips is arranged in the hold 2 almost from the bow to the stern. In addition, a space 3 is formed and arranged in the lower part of the storage 1 over its entire length, and a horizontally rotating wheel 5 is placed on the bottom wall 4 of the storage 1 that forms the bottom of the space 3. By running the plurality of storages 1 in the parallel direction, the bulk material 6 in the storage 1 is discharged below the bottom wall 4 through a slit-shaped outlet 7 continuously formed on the bottom wall 4. There is known a bulk carrier having a bulk dispensing device 9 for dispensing on a dispensing conveyor 8 arranged along the outlet 7.
[0003]
In a bulk carrier having such a bulk material delivery device 9, bulk material delivered on the delivery conveyor 8 is transported to the ship by a vertical conveyor 10 disposed at the bow, for example, and is carried out of the ship by the boom conveyor 11. Thus, the bulk material in the storage 1 can be automatically unloaded.
[0004]
In such a bulk carrier, the storage tank 1 may be divided into a plurality of storage tanks 1a, 1b, 1c, and 1d in the traveling direction for the purpose of transporting various types of bulk goods.
[0005]
When a plurality of storage tanks 1a, 1b, 1c, and 1d are arranged in parallel as described above, different types of loose pieces 6a, 6b, 6c, and 6d are loaded on the respective storage tanks 1a, 1b, 1c, and 1d. There is an advantage that it can be transported.
[0006]
And when it is desired to unload only the bulk material 6b in the storage tank 1b among the parallel storage tanks 1a, 1b, 1c, 1d, it is paid out by reciprocating the wheel 5 in the storage tank 1b. It is.
[0007]
[Problems to be solved by the invention]
However, when the wheel 5 is reciprocated, the loose material 6a or 6c in the storage tank 1a or 1c is slightly discharged when the center of the wheel 5 reaches the folding position on the storage tank 1a or 1c side. Thus, there is a problem that different types of bulk materials 6a and 6c are mixed with the bulk material 6b in the storage tank 1b to be selectively unloaded.
[0008]
[Means for Solving the Problems]
The present invention was made in order to solve the above-mentioned problems of the conventional bulk dispensing apparatus, and a space is formed through each of the storage tanks at the bottom of a plurality of parallel storage tanks. And by moving a horizontally rotating wheel in the parallel direction of the plurality of storage tanks on the bottom wall of the storage tank forming the bottom of the void, through the bottom wall to continuously said cavity slit-like discharge opening formed along, in the loose material dispenser to pay out on the bottom wall of the dispensing conveyor which is disposed along the dispensing opening in the lower In the bottom wall, a slit for preventing the mixing of loose materials that intersects with the outlet is formed at the boundary of each storage tank.
[0009]
By configuring in this way, when the wheel is reciprocated along a specific storage tank, the wheel is paid out from the adjacent storage tank when the center of the wheel reaches the turnaround position on the adjacent storage tank side. A small amount of different types of bulk material is drawn to the side of a specific storage tank according to the traveling wheel, and at the same time crosses a slit-shaped discharge outlet formed along the discharge conveyor at the boundary of the storage tank on the bottom wall. Since it falls from the formed slit for preventing mixing, there is no fear of mixing with the bulk material in the specific storage tank that is dropped onto the discharge conveyor and selectively unloaded.
[0010]
In addition, when a mixing prevention conveyor is disposed between the bottom wall and the payout conveyor along the mixing prevention slit, different types of loose materials falling from the mixing prevention slit can be easily and reliably collected. Is possible.
[0011]
Furthermore, when the mixing prevention conveyor is operated only when the wheel approaches the boundary between the storage tanks, it is possible to reduce power costs caused by continuous use and prevent early deterioration. .
